Connect to Fiserv

This guide outlines the necessary steps to connect your Pagos and Fiserv accounts. For more information on connecting Pagos to other payment processors, see our Connecting Your Payment Processors to Pagos guide.

After you successfully connect your accounts, we’ll import your payments data from Fiserv into Pagos once a day via a secure file transfer protocol (SFTP), starting with the first day of the successful connection. We can also import historical payments data upon request; reach out to your Pagos account team and dLocal relationship manager for more information.

Connecting Fiserv to Pagos

To send payments data from your Fiserv account to Pagos, ask your Fiserv team to set up a new designated CLX SFTP mailbox. Even if you already have a CLX mailbox, we recommend setting up a new one specifically for connecting to Pagos.

Once you establish the mailbox, schedule all fields to be automatically generated on a daily basis for the following data types:

  • Authorizations (CSV format)
  • Chargebacks (XLS format)
  • Inquiries (CSV format)
  • Settlement (CSV format)
  • Funding (CSV format)



You’ll need to name both your schedules and the files themselves within your Fiserv account; we recommend naming them something related to Pagos for easy identification in the future.
